Following the first GOP debate, many Republicans are questioning whether Donald Trump has what it takes to lead the country in a post 9/11 world. Adam Goodman joined co-panelist Jane Hampton Cook, a Presidential historian, on the O’Reilly Factor to discuss.

As Trump breaks every rule in the book at the start of the race, Goodman says his habit of putting problems out there without solutions may cause more problems down the line.

“He’s playing completely outside the lines right now,” says Goodman. “At some point, I think we’ll move from entertainment to a true desire to find who’s going to lead. Now, he does check a number of boxes [for GOP voters], but so does Carly Fiorina… so there are others who can take this role.”

Goodman says an obstacle for Trump is durability once America gets closer to the primaries.

“People want something. They’re looking for something visceral, fresh, and different, and I don’t think that, frankly, Donald Trump is going to wear well over time.”

Eventually, Republicans will have to take stock of what other candidates have to offer, even if they don’t bring the entertainment factor the way Trump can.
